I have a data set of about 160,000 and 25 attributes - trying to detect outliers for numeric variables using detect outliers operators but seems to take for ever to run and sometimes simply runs out of memory

Any advice on a more efficient way to identify outliers in a data set using RapidMiner Studio would be much appreciated

AH I meant the Anomaly Detection extension. Ok, so you have it installed already. My guess is that the memory available to RapidMiner is not enough. How much do you have and what is your license type? Community? Educational?
